I have ripented the map to fix unsupported characters at the end of the wad list in worldspawn. This fixes the map crashing on startup.

Note that because monster riding was removed after 3.0, the map won't work as intended. You're supposed to ride a snark to the end of the track, and then you get teleported to first/second/third place depending on who wins first. Since you can't ride a snark in the current version of the game, you touch the race track floor and die.
